For the following problem, do not use algebra. Make a guess that satisfies one or more conditions of the problem, and then evaluate your guess. You must show work to support your solution, for example, use a table to document your guesses. Rick, Sam, and Li work at a coffee shop for a total of 59 hours. If Rick worked 5 more hours than Sam and 4 fewer hours than Li, how many hours did Li work? a. Use your own words to describe the big-picture ideas from the given scenario. b.

This will be my final puzzle of this series and is not math. You need to fill in the blanks with one of the letters from the first line. The rules are that no two of the letters can appear in a line (horizontal, vertical, or diagonal). For example if you draw a line either horizontal, vertical, or diagonal and it passes through any duplicate letter, one of the duplicates must be moved. You will not be able to fill all the blanks. The winner is the one with the least number of blanks. 100 pesos to the person with the least number of blanks.
A tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race.
